OIL-BURNER.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed October 7, 1909. Serial No. 521,460.

To all whom it may concern:

Be it known that I, CHAnLns D. WRIGHT, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Oil-Burners, of whichthe following is a specification.

This invention relates to improvements in that class of burners, inwhich oil is used for fuel, and while it is more especially intended foruse, and will hereinafter be referred to as an oil-burner in connectionwith a heater or stove, yet it is applicable for use with slight andobvious changes in other kinds of appliances which require heat, and itconsists in certain peculiarities of the con struction and novelarrangement of the various parts thereof, as will be hereinafter morefully set forth and specifically claimed.

The principal object of the invention is to provide an oil-burner of theabove-named general character, which shall be simple and inexpensive inconstruction, strong, durable and effective in operation, and also madein such a manner that a downwardly directed draft to the burner, will beafforded, to the end that almost perfect combustion will be attained,thus preventing the loss of fuel in the form of smoke, and 'unconsumedparticles of carbon.

A further object of the invention is to provide an oil-burner which maybe readily installed in almost any kind of a heater or stove withoutmaterially altering the parts of the same, and which can be readilyremoved therefrom for the purposes of cleaning or renewing the parts.

Other objects and advantages of the invention will be disclosed in thesubjoined description and explanation.

In order to enable others skilled in the art to which my inventionpertains, to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which- Figure 1, is a centralvertical sectional view of an oil-burner embodying the invention,showing it in position within a heating stove. Fig. 2, is a centralvertical sectional view of a heater or stove showing a burner embodyingthe invention, mounted therein, and illustrating a modification in themanner of supplying the fuel oil there to. Fig. 3, is an enlarged viewpartly in section and partly in elevation of a portion of a stove casingand the burner mounted on the grate thereof. Fig. 4, is an enlargedcentral vertical sectional view of the burner showing it detached. AndFig. 5, is a hori zontal sectionalview taken on line 55 of Fig. 4.

Like numerals of reference refer to corresponding parts throughout thediflferent views of the drawings.

The reference numeral 8, designates a stove or heater which may be madeof any suitable size, form and material, but preferably cylindrical inshape as shown. The lower portion of the stove or heater 8, is providedwith a horizontally disposed grate 9, of the ordinary or any desiredconstruction, on which may be placed a metal plate 10, to support thebase piece or receptacle 11, of the burner, which receptacle ispreferably made of cast-iron, and may be of any suitable size and shape,but preferably cylindrical, as shown.

for firmly holding the base piece 11, in position. Located within thereceptacle 11, is

the burner, which is designated as a whole by the reference numeral 13,and which is hollow and cylindrical in shape, or of a shape tocorrespond with the base piece or receptacle 11, in which its lowerportion is fitted. The burner 13, is closed at its bottom, but has itsupper end open, and is provided between its ends with a series ofopenings 14: for the passage of the drafts of air and flames from theburning fuel. These openings are usually and preferably located justabove the receptacle 11, and by prefer ence are disposed horizontally asis clearly shown in Figs. 2, and 3, of the drawings. The bottom of theburner body 13, is provided at about its center with an upwardlyextended boss '15, having a socket 16, to re ceive the lower end of thestem 17, of the vaporizer or spreader 18, which is mounted on the upperend of said stem and is preferably provided with a slight cavity ordepression 19, in its upper portion to hold a small quantity of oil. Thelower portion of the spreader or vaporizer 18, is also preferablyprovided with an upwardly extended cavity 20, which surrounds the upperportion of the stem 17 and is for the purpose of allowing flames andheat to enter the same so as to more quickly heat the spreader orvaporizer.

' Horizontally mounted on the stem 17 below the vaporizer 18, is ashallow cup 21, which is larger in diameter than the vaporizer 18,andwill catch and retain oil as it falls from the vaporizer, where itcan be ignited when the burner is first put in operation. Resting on thetop of the burner body 13, is a dome-shaped cover 22, which has in itsupper portion an opening 23, to receive the lower end of the draft-pipe24:, which is extended at its upper end through the top of the stovecasing and is by preference slightly tapered from its upper enddownwardly, as is clearly shown in Fig. 1, of the drawing. Thisdraft-pipe is employed for the purpose of furnishing the downwardlydirected draft of air to the burner, and also for the purpose ofpermitting oil to bepa'ssed therethrough, from a feed pipe 25, which maybe connected to a source of oil supply (not shown) and provided with avalve 26, to regulate the flow of oil therethrough.

In Fig. 2, of the drawings, is shown a modification in the means forsupplying oil to thevaporizer and burner, which consists in extending adraft-pipe 246, from the upper portion of the cover 22 of the burnerbody tothe wall of the stove 8, so as to afford communication throughthe side of the stove, with the cover 22, instead of through the top ofthe stove as shown in Fig. 1, and above described. In this modification,a feed pipe 25 which may have communication at one of its ends withasupply of 'oil, (not shown) is extended into the draft-pipe 245*, andmay be supported at a distance therefrom within the same in any suitablemanner, but usually by means of spider-like supports 27 located atsuitable points within the draft-pipe. In this modified construction,the feed-pipe 25 is provided with a valve 26 to control the flow of oilthrough said pipe.

As shown in Fig. 5, the burner body 13, is provided on its outer surfacewith a series of vertically disposed ribs 28, which will hold the mainportion of said body, at a slight distance from the receptacle 11, thusforming an air-space between the two parts.

From the foregoing and by reference to the drawings, it will be readilyunderstood and clearly seen that oil may be turned on by means of thefeed-pipe and its valve, when it will strike the top of the vaporizer orspreader, where it may be ignited by means of a match or otherwise, andcontinue to burn as the oil is fed or supplied to said vaporizer, or cup21, below the same, when the burner body 13, vaporizer 18, cup 21, andcover 22, will become heated and form gas within the dome-like cover andbody of the burner.

In the operation of the burner, air will pass down the draft-pipe andout through the openings 14, in the burner body into the stove casing,and it is apparent that the products of combustion may escape throughsuitable openings 29, in the top of the stove when the constructionshown in Fig. 1, is employed, or through an outlet pipe 30, in the upperportion of the stove when the construction shown in Fig. 2, is used. Byusing the base 11, which is held at a slight distance from the lowerportion of the body 13, it is apparent that an air space between thesame will be afforded and that as the base 11, is protected externallyby means of the material 12, such as fire-clay, or the like, it, as wellas the lower portion of the body, will be protected from the intenseheat generated by the burning gases and oil, thus rendering the devicemore durable.

It will be understood that the invention is susceptible of considerablemodification, without departing from the principles and spirit thereof,and for this reason, I do not desire to be understood as limiting myselfto the exact construction of the parts herein shown, and set forth.

Having thus fully described my invention what I claim as new and desireto secure by Letters-Patent is 1. An oil burner consisting of a hollowbody having an opening between its upper and lower ends and adapted tobe supported within the stove or heater, an apertured cover for saidbody, a vaporizer located within the body below the opening in saidcover, a cup suitably supported wlthin the body below the vaporizer, adraft-pipe communicating through said cover with the body, and means tosupply oil to the vaporizer.
